David Attenborough: A Life on Our Planet

David Attenborough calls the film his witness statement — showing how the planet has changed over his lifetime. He tracks three numbers: population growth, rising CO₂, and shrinking wilderness.

The first half highlights what’s been lost: biodiversity, forests, coral reefs, and stable climates — calling it a human-driven “sixth mass extinction.”

The second half offers solutions: restoring nature, rewilding land and oceans, shifting to plant-rich diets, stabilizing populations through education, and transitioning to renewable energy.

The message: we caused the crisis, but we also have the tools to fix it — if we act now.
